Hybrid polymer electrolytes electrochemical devices

Abstract The interest in sol-gel derived polymer/siloxane hybrid electrolytes has grown considerably during the last decade because of their potential application in sohd state electrochemical devices, in particular batteries and electrochromic devices (ECDs).This review intends to provide an overview of the latest advances in the investigation of the structure, morphology, thermal properties, electrochemical behavior and spectroscopic features of Li -coutaiuiug di-urea crosslinked polyoxyethylene (POE)/siloxane (di-ureasil) electrolytes. Applications of these materials in ECDs will be addressed.

An electrochemical capacitor is a device that stores electrical energy in the electrical double layer that forms at the interface between an electrolytic solution and an electronic conductor. The term applies to charged carbon—carbon systems as well as carbon-battery electrode and conducting polymer electrode combinations sometimes called ultracapacitors, supercapacitors, or hybrid capacitors.
